Bitcoin vs. Bitcoin Cash: A comparison of two cryptocurrency paths

May 8, 2024

In the rapidly evolving world of cryptocurrencies, few topics have been as hotly debated as the split between Bitcoin and Bitcoin Cash. This prominent split has not only divided the crypto communities, but has also led to in-depth discussions about the fundamental principles of Bitcoin itself. What began as a debate over technical specifications has evolved into a philosophical battle over what Bitcoin should represent and how it can best serve its users in a digital age.

This blog post explores the core differences between these two major currencies and explores the philosophies that set them apart. The goal is to give both investors and technologists, and really anyone interested in the future of digital payments, a clear picture of the unique paths taken by Bitcoin and Bitcoin Cash. Choosing between them can have profound implications for your personal or financial goals, depending on your needs in terms of transaction speed, cost, and technological advancement.

Origin of debate

The debate around Bitcoin's capacity limits began with a simple technical question: how can the Bitcoin network efficiently scale to meet growing demand? The initial limit of about 1 MB per block was intended to prevent spam attacks, but became a bottleneck as the number of transactions increased. This brought up the question that even Satoshi Nakamoto, Bitcoin's mysterious creator, might have considered: how do you maintain Bitcoin's decentralization and functionality while expanding the network?

The Divide: The Birth of Bitcoin Cash

This capacity limitation led to deep divisions within the community. While one group of proponents wanted to increase the block size to 8 MB to ease congestion and lower transaction costs-resulting in the creation of Bitcoin Cash during a hard fork in 2017-another group lagged behind the original Bitcoin, leading to a reflection on what Bitcoin fundamentally represents: a store of value or a medium for daily transactions?

Bitcoin's approach: Segregated Witness

Bitcoin chose a less direct but more technically advanced route with Segregated Witness (SegWit), which allowed more transactions within the same block size by processing certain information outside the main block. This approach was reinforced by the Lightning Network, which makes transactions faster and cheaper by processing them off-chain. These developments were answers to Nakamoto's demand for scalability without compromising decentralization.

Philosophical differences

While Bitcoin Cash focuses on direct on-chain transaction processing with larger blocks, Bitcoin sticks to a model that limits block size and relies on off-chain solutions for scalability. This difference in approach reflects a deeper philosophical split on what it means to stay true to Satoshi's vision: should Bitcoin remain a digital gold or evolve into a more efficient, accessible electronic cash system?

Bitcoin continues to innovate with developments such as Schnorr signatures and the Taproot upgrade, which further improve the privacy and efficiency of transactions. Bitcoin Cash continues to focus on increasing block size and supporting smart contracts to facilitate daily transactions. Despite technological advances, Bitcoin remains the market leader, while Bitcoin Cash aims to increase adoption through its lower costs and faster transaction confirmations.


The choice between Bitcoin and Bitcoin Cash is not just a technical consideration, but touches on fundamental questions about what cryptocurrencies should be and how they can improve our daily lives. This choice requires you to think about your personal vision of decentralization, scalability and daily usability of digital currencies.

If you value fast and cheap transactions for everyday purchases, you might find that Bitcoin Cash, with its larger block size and lower transaction fees, better suits your needs. Bitcoin Cash strives to realize the original vision of an electronic peer-to-peer cash system, a vision focused on maximum accessibility and ease of use.

On the other hand, if you prefer an asset that serves not only as a medium of exchange but also as a robust store of value, Bitcoin with its extensive network effect, higher security measures, and less volatile market position offers a compelling option. Bitcoin remains the most recognized and valued cryptocurrency, often seen as "digital gold.

Both currencies continue to evolve and adapt to new technological challenges and market needs, contributing to the rich diversity of the cryptocurrency ecosystem. How the future of these technologies will unfold depends in part on the choices of individual users like you, who determine the path these currencies will take.
